Data routing in a content distribution network for mobility delivery

ABSTRACT

System(s) and method(s) are provided to route data within a network of content with specific service constraints to mobile devices. A mobile network management component receives an identifier (ID) of a base station that serves a mobile device that originates a request for data, and relays the ID to a network platform that administers content. A mapping that associates one or more base stations with a deployed content node and the received ID are utilized to identify a content node to serve the request for data via the base station. The received request for data is directed to the identified content node. A service constraint configuration can be allocated for exchange of payload data between the mobile device and the network platform. For a request to consume data and a request to supply data, identified content node delivers data and receives data, respectively, in accordance with the service constraint allocation.

TECHNICAL FIELD

The subject disclosure relates generally to communication networks and, more specifically, to networked distribution of content or data with specific service constraints to mobile devices.

BACKGROUND

A Content Distribution Network (CDN) deploys a large number of servers in geographically distributed areas, content (e.g., web pages, files, email messages, media . . . ) from a content provider can be cached in the deployed servers, so that the content can be delivered efficiently and quickly to end-users in response to a request for data therefrom. Delivery of cached content generally can avoid delays due to slow transport or congested backhaul links at the time of the request, and can prevent overload of the content provider's servers if the number of requests for data is substantive. In a conventional CDN, content is made available to end-users according to the end-users' location within a space of logical addresses, such as internet protocol (IP) addresses, for the mobile device, as well as other factors, such as network load, e.g., cache server's load, or other parameters relevant to the content provider's preferences. The conventional CDN utilizes information on the IP address of a device associated with the end-user, as well as the other parameters to determine a cache server, or CDN node, from which a request for data from an end user is to be served.

When the device from which an end-user requests for data, e.g., content, from the conventional CDN is a mobile device, such as a phone, the request for content is delivered from the mobile phone to a nearby base station of a mobile service provider in the geographical area in which the mobile device operates. From the base station, the request is sent over the service provider's core network to an access network, such as the Internet, through which the request for data is delivered to the conventional CDN. As indicated supra, the CDN determines to which CDN node to send the request for data based primarily on the IP address of the end-user's device, namely, the IP address of the mobile phone. Since such IP address is assigned dynamically when the mobile device initiates a data session, e.g., connects to the internet, substantial signaling is incurred as a result of routing data from the CDN to the mobile device, with the ensuing increase in control traffic and processing at the CDN servers, which thus renders conventional data routing in CDN largely inefficient.

SUMMARY

The following presents a simplified summary of the subject disclosure in order to provide a basic understanding of some aspects thereof. This summary is not an extensive overview of the subject disclosure. It is intended to neither identify key or critical elements nor delineate any scope. Its sole purpose is to present some concepts of the various embodiments of the subject disclosure in a simplified form as a prelude to the more detailed description that is presented later.

One or more embodiments provide data routing or organization of data exchange in a network of content for mobility delivery. The one or more embodiments can allow optimization of performance of data exchange amongst a mobile device and the network of content, e.g., content distribution network. In the alternative, such data exchange can be conducted within a satisfactory level of performance. In an aspect, the network of content is embodied in a content distribution network (CDN) which comprises a CDN platform and a set of remotely deployed CDN nodes; one or more CDN nodes in the set are operationally linked to one or more base stations. To route or organize data exchange, a mobile network management component, which can reside within a core network of a cellular wireless network or a service network external to the wireless network, receives an identifier (ID) of a base station that serves a mobile device that originates a request for data. The request for data can be a request to consume content or to supply content. The mobile network management component relays the ID to a network platform that administers content, e.g., the CDN platform. A routing component within the network platform identifies a content node, e.g., a CDN node, through a mapping that associates one or more base stations with a deployed content node, and the received ID; the identified content node serves the request for data. In addition, the routing component can allocate a service constraint, or quality of service (QoS), configuration, for exchange (e.g., transmission or reception) of payload data between the mobile device and the network platform. To serve data, or content, to the mobile device, the identified CDN node receives the request for data and the service constraint configuration. For a request to consume data and a request to supply data, identified content node delivers data and receives data, respectively, in accordance with the service constraint allocation.

Furthermore, the terms “end user,” “subscriber,” “customer,” “consumer,” “prosumer,” “agent,” and the like are employed interchangeably throughout the subject specification, unless context warrants particular distinction(s) among the terms. It should be appreciated that such terms can refer to human entities or automated components supported through artificial intelligence (e.g., a capacity to make inference based on complex mathematical formalisms) which can provide simulated vision, sound recognition and so forth. When utilized, the term “prosumer” indicates the following contractions: professional-consumer and producer-consumer.

Further yet, the term “set” as employed herein excludes the empty set. Thus, a “set” in the subject disclosure includes one or more elements or entities. As an illustration, a set of base stations includes one or more base stations, a set of content distribution network (CDN) nodes includes one or more CDN nodes, or the like.

It is noted that features or aspects described in the subject disclosure can rely, at least in part, on delivery or reception of indication(s), directive(s), request(s), or the like, and information or payload data (e.g., content(s)) associated therewith. Indication(s), directive(s), or request(s) can be embodied in multi-bit words (e.g., P-bit words, with P a positive integer) and coded to specifically convey a request(s) to a particular functional element (e.g., a CDN node) in order to execute specific operation(s) or configure particular service(s) (e.g., quality of service (QoS) configuration).

Additionally, various aspects of the subject disclosure are presented in terms of systems or embodiments that may include a number of components, modules, nodes, interfaces, platforms, or the like. It is to be understood and appreciated that the various systems or embodiments may include additional components, modules, etc. and/or may not include all of the components, modules, nodes, interfaces, platforms, etc. discussed in connection with the annexed drawings. A combination of these approaches may also be used.

As described in greater detail below, one or more embodiment of the subject disclosure can enable data routing within a network of content with specific service constraints to mobile devices. The one or more embodiments can allow optimization of performance of data exchange amongst a mobile device and the network of content, e.g., content distribution network. In the alternative, such data exchange can be conducted within a satisfactory level of performance A mobile network management component receives an identifier (ID) of a base station that serves a mobile device that originates a request for data, and relays the ID to a network platform that administers content. A mapping that associates one or more base stations with a deployed content node and the received ID are utilized to identify a content node to serve the request for data via the base station. The received request for data is directed to the identified content node. A service constraint configuration can be allocated for exchange of payload data between the mobile device and the network platform. For a request to consume data and a request to supply data, identified content node delivers data and receives data, respectively, in accordance with the service constraint allocation.

To route data and regulate (e.g., increase) service constraints, or quality of service (QoS), the one or more embodiments described herein advantageously exploit aspects or features that are intrinsic to, yet not limited to, interaction amongst a content distribution network (CDN) and a mobile network. In particular, though not exclusively, aspects or features include the following. (1) End-user data, e.g., traffic, and control data, e.g., signaling, in mobile communications are transmitted or received through a base station administered by a telecommunication carrier or mobile service provider, wherein the location of the base station which is fixed in geographical location. (2) CDN nodes also are in fixed or substantially static in geographical locations, and deployment density of CDN nodes (number of commissioned CDN nodes per unit area) is generally lower than deployment density of base stations (e.g., number of provisioned and active base stations per unit area).

With reference to the drawings, FIG. 1 is a block diagram of an example system 100 that enables routing of content in a content distribution network (CDN) based in part on base station deployment information. In the subject example system 100, a mobility management (MM) component 110 is functionally connected through link(s) 115 to base station(s) 120, which comprises a set of one or more base stations deployed in a macrocellular coverage area. In an aspect, mobility management component 110 can be embodied in a gateway node (e.g., Gateway GPRS Support Node (GGSN)), a Serving GPRS Support Node (SGSN), Mobility Management Entity (MME)), a Session Border Control (SBC) node, an application server, or the like. Accordingly, in one or more embodiments, MM management component 110 can include a processor that executes code instructions to provide, at least in part, the functionality described herein. One or more base stations within base station(s) 120 can receive a request for data from a device 130, mobile or otherwise, which can communicate wirelessly, through wireless link(s) 125, with the one or more base stations; the request for data can be at least one of a request to consume (e.g., download) data or a request to supply (e.g., upload) data. At least the one or more base stations that receive the request for data can serve it, e.g., deliver or receive content, e.g., payload data, in response to the request for data. To receive or deliver data (e.g., traffic, signaling), in an aspect, the one or more base stations, which are part of base station(s) 120, can include a communication platform and associated circuitry and antenna(s), a processor, and a memory, wherein the processor can execute code instructions retained in the memory in order to provide the functionality of the base station as described herein. In addition, the circuitry associated with the communication platform, via at least in part the processor, can process (e.g., modulate, demodulate, multiplex, demultiplex, . . . ) signal(s) received, or to be conveyed, through the antenna(s) in the communication platform. Processing of the signal(s) can proceed in accordance with one or more telecommunication protocols associated with one or more radio technologies, such as those indicated supra.

A content distribution network (CDN) provides the served content, or payload data. In an aspect of the subject disclosure, the content distribution network comprises a CDN platform 150 functionally connected to MM component 110 through an interface 145, and CDN node(s) 170, which comprises a set of CDN nodes deployed in one or more geographical areas. Interface 145 can include at least one of a conventional wired link, a wireless link, or a reference link and associated component(s). In one or more embodiments, interface that can include at least one of a conventional wired link, a wireless link, or a reference link and associated component(s). Link(s) 165 functionally connect CDN platform 150 to CDN node(s) 170. In addition, CDN node(s) 170 are functionally connected to base station(s) 120 through one or more interfaces 175, which can include at least one of a conventional wired link, a wireless link, or a reference link and associated component(s).

To deliver content to or receive content from device 130, the CDN utilizes information on deployment of base station(s) 120 and relationship(s) between the deployment of the base station(s) 120 and CDN nodes 170. The relationship(s) can allow optimization of communication amongst device 130 and the CDN through optimization of selection of a CDN node to serve a request for data. In an aspect, CDN platform 150 exploits, at least in part, content server(s) 152 in addition to routing component 154 and mapping component 156. While in example system 100 content server(s) 152 are illustrated as external to routing component 154 and mapping component 156, in one or more embodiments, one or more of routing component 154 and mapping component 156 can be included within one or more content server(s). Routing component 154 receives a request for data from mobility management component 110, and exploits a mapping that associates a set of base stations (e.g., base station(s) 120) in a wireless macrocellular network with deployed CDN node(s) 170 to identify or to select a CDN node that can serve, at least in part, the request for data. As an example, routing component 154 can inspect a look-up table that embodies the mapping and is retained in memory 160 within mapping(s) 162; to inspect such look-up table, routing component 154 can execute, at least in part, code instructions (not shown) retained in memory 160. In one or more additional or alternative embodiments, mapping component 156 can be configured to identify or select, or can identify or select, the CDN node that can serve, at least in part, the request for data. In such one or more embodiments, the mapping component 156 can supply an identification of the identified or selected CDN node to routing component 154. The identification can be supplied in response to a request from routing component 154 to identify or select a suitable CDN node to serve a request for data.

After a suitable CDN node has been selected or identified, routing component 154 directs the request for data to the selected or identified CDN node. When device 130 is a mobile device, it should be appreciated that the subject routing effected by routing component 154 transforms the problem of dealing with a logical address (e.g., internet protocol (IP) address) allocated to device 130 and that changes due to mobility thereof to dealing with a fixed or substantially fixed logical address (e.g., IP address) of the base station that serves the device 130, wherein the logical address of the base station and a serving CDN node linked thereto can be readily extracted from the aforementioned mapping, e.g., a look-up table.

The request for data received by routing component 154 can be a request to supply data or to consume data, and can include an identifier (ID) for the base station within base station(s) 120 that receives the request for data from device 130. In one or more scenarios, a base station ID can be a composite entity that includes an internet protocol (IP) address of the base station in addition to a wireless network ID, e.g., cell identity, for the base station. In the mapping, a single logical address (e.g., internet protocol (IP) address) of a CDN node can be linked to one or more base station IDs. To identify or select a suitable CDN node, routing component 154 can access the mapping directly or via mapping component 156; the mapping can be retained in memory 160 within mapping(s) storage 162, also referred to herein and in annexed drawings are mapping(s) 162. To access the mapping via mapping component 156, routing component 154 can deliver a directive to provide data and receive the requested data from mapping component 156 in response to the directive. Routing component 154 can access the mapping when it executes, at least in part, routing algorithms or implements, at least in part, routing methods, which can include one or more of the example methods described herein. Routing algorithms or routing methods can be retained in algorithm store 164.

In another aspect of the subject disclosure, since the request for data conveys a base station ID and such conveyance indicates that a mobile device originates the request for data, routing component 154, via, e.g., a service configuration component (not shown), can configure a service constraint for exchange (e.g., delivery or reception) of payload data solicited in the request for data. The service constraint, or service constraint indication, can include a quality of service (QoS) class, or a predetermined bit rate or upper or lower bound thereof. In an illustrative scenario, to configure or generate a service constraint, routing component 154, through the service configuration component (not shown), for example, can (i) assess at least one of volume of data requested to be delivered (e.g., downloaded) or received (e.g., uploaded), subscriber class (e.g., business or personal) of device (e.g., 130) that originates the request for data, or network conditions (e.g., load, channel quality conditions), and (ii) determined a QoS class or bit rate to serve the request for data. To conduct such assessment, routing component 154, via service configuration component (not shown), can exchange data with MM component 110, which can access database(s) 140, to supply requested information, such as wireless network conditions or subscriber class. Routing component 154, e.g., via the service configuration component (not shown), can supply an indication of the service constraint, or QoS class, to at least one of a CDN node identified, or selected, as part of routing data in response to the request for data. The CDN node can relay the service constraint, or service constraint indication, to the base station that is associated with the CDN node in accordance with a mapping employed to route data in response to the request for data. Accordingly, routing component 154 can provide QoS to a mobile device, e.g., 130, that submits a request for data to a CDN. Providing QoS class, or service constraint(s), also can optimize data exchange, e.g., transmission, of data amongst the mobile device, e.g., 130, that submits the request for data and the CDN node that serves, at least in part, the request for data.

If a request for data is a request to consume, e.g., download, data, a CDN node within CDN node(s) 170 that is identified by routing component 154 based at least in part on a base station ID and a mapping can receive the request for data and a QoS configuration, and can transmit data solicited in the request for data, wherein the transmission is performed in accordance with the QoS configuration. The CDN node transmits the data to an associated base station within base station(s) 120 that serves telecommunication with device 130, the base station relays the data received from the CDN node to the device 130, which originated the request for data.

In the alternative, if the request for data is a request to supply data, e.g., upload data, a CDN node within CDN node(s) 170 that is identified by routing component 154 based at least in part on a base station ID and a mapping can receive the request for data and a QoS configuration and can deliver an indication to serve the request for data in accordance with the QoS configuration. Such indication is delivered to a base station that is associated with the CDN node, via the mapping, and serves telecommunication with device 130, which originated the request for data. The base station delivers a request for payload data consistent with the request for data, e.g., the request to upload data, and in response the device 130 provides the payload data. The base station receives the payload data and relays such data to the CDN node associated with the base station; the CDN node forwards the payload data to the routing component 154, which retains the data in a memory functionally coupled with a CDN platform (e.g., 154) or a content server (e.g., 152) that includes the routing component 154.

As indicated supra, the mapping characterizes the relationship(s) between the deployment of the base station(s) 120 and CDN nodes 170, and can provide identification or allow selection of a CDN node that is geographically closest or sufficiently geographically close (e.g., based in part on predetermined operation criteria) to a specific base station. A mapping is established before a request for data is served and can optimize performance or accomplish a satisfactory level of performance of service of the request for data via selection of CDN node associated with a base station that receives the request for data from device 130. In an aspect, performance optimization or performance within a satisfactory level can be measured against objective metrics such as a communication costs. Apart from temporary distribution network congestion or special service requests from an administration of the content, or the content owner, lowest communications costs for content to be delivered to a mobile device connected to a base station can be obtained if the CDN node closest to the base station is utilized to serve a request for data.

A mapping associates a base station(s) 120 to CDN node(s) 170 in a one-to-one relationship or a many-to-one relationship. In an aspect, many-to-one relationships within a mapping can be common because density of CDN node deployment can be typically lower than density of base station deployment. The mapping can be configured and upgraded as base station deployment or wireless network plan(s) are modified; however, in common scenarios, base station location and location of a related CDN node remains largely unchanged because a provisioned base station and a CDN node remains in substantially unchanged locations, or geographical loci. To generate a mapping, mapping component 156 can receive deployment information—e.g., information retained in network plan 142 in database(s) 140—from mobility management component 110 and associate such deployment information with knowledge of CDN node deployment or configuration within the CDN in order to form a mapping that associates one or more base stations with a geographically closest or sufficiently close CDN node. The deployment information can include base station identifiers (IDs), such as cell identities, which are generated at a time a base station is provisioned and activated in a macrocellular network. Mapping component 156 can commit a mapping to memory 160. In an aspect, database(s) 140 can be embodied in one or more of a Home Subscriber Server (HSS), a Home Location Register (HLR), a Visitor Location Register (VLR), a backend service database, or the like. Database(s) 140 can be functionally connected mobility management component 110 through an interface that can include at least one of a conventional wired link, a wireless link, or a reference link and associated component(s). In another aspect, network plan 142 can be updated at predetermined intervals or based on events such as updates to a wireless network that includes and administers MM component 110.

Features or aspects of the subject disclosure and one or more embodiments thereof have at least the following advantages with respect to conventional data routing in content distribution networks. (i) When compared to selection of a CDN node through calculation of location of a mobile device that originates a request for data based on the mobile device's allocated IP address, utilization of knowledge of deployment (e.g., location) of base stations in a macrocellular network reduces the time necessary to select a CDN node to serve a request for data. As indicated supra, deployment information can be largely static or it can be changed in time scales much larger than time scales in which IP address(es) of a mobile device is updated due to mobility. (ii) Optimization of selection of a CDN node to serve a request for data, e.g., deliver content requested by a mobile end-user, results in shorter fulfillment time, e.g., delivery time to the end-user, and therefore it can lead to improved end-user experience. (iii) Allocation, e.g., configuration and provisioning, of service constraint(s) or QoS for a device that communicates wirelessly and originates a request for data can result in shorter fulfillment time, e.g., delivery time from CDN to the end-user or upload time to CDN from end-user device, and therefore improved end-user experience. In general, at least the subject advantages can result in improved end-user experience, which can translate in increased end-user perceived quality of service with respect to the CDN service provider, e.g., an administrator of CDN platform 150 or CDN node(s) 170 and can generate a potential business differentiator.

FIG. 2 illustrates a diagram 200 of example embodiments of a content server that can be part of CDN platform 150 and CDN nodes in accordance with aspects described herein. Content server 210 can embody one or more of the content servers that are part of content server(s) 152 within CDN platform 150. In an aspect, content server 210 includes routing component 154 and mapping component 156, both of which can be configured to operate or can operate as described hereinbefore. As part of a CDN platform (e.g., 150), content server 210 can transmit at least a portion of content (e.g., media or other type of digital files) retained in data store 220 as part of content(s) 224 to one or more of CDN nodes 230 ₁-230 _(M), with M a natural number; content(s) 224 retained in memory 218 can be supplied to end-user devices, mobile or otherwise, as part of a content supply service. The portion of content that is transmitted is cached or stored within a memory that is part of the CDN node that receives the portion of content. As an illustration, content χ 226 can embody the portion of content and can be delivered to CDN nodes 230 ₁ and 230 ₂ and retained, respectively, in data cache 238 ₁ and data cache 238 ₂. Content χ 226 so retained in CDN nodes 230 ₁ and 230 ₂ can be accessed by disparate end-user devices (not shown in FIG. 2). In such illustration, CDN nodes 230 ₃ (not shown) through 230 _(M) do not receive content χ 226.

FIG. 3 is a diagram that illustrates example communication paths in an example environment 300 that operates in accordance with aspects described herein. Two CDN nodes 302 ₁ and 302 ₂ are functionally connected, respectively, to a base station 304 ₁ and a set of three base stations {304 ₂,304 ₃,304 ₄}; in a one-to-one relationship, CDN node 302 ₁ connects to base station 304 ₁ via an interface 306 ₁, whereas in a many-to-one relationship, CDN node 302 ₂ connects to base stations 304 ₂,304 ₃,304 ₄ through respective interfaces 306 ₂, 306 ₃, and 306 ₄. Interfaces 306 ₁, 306 ₂, 306 ₃, and 306 ₄ operate in the same or substantially the same manner as interface(s) 175. CDN nodes 302 ₁ and 302 ₂ are functionally coupled to CDN platform 150 via link(s) 165. In a first example scenario, device 310 downloads content from CDN platform 150. Communication path for such download of content is illustrated with arrow 314. As described supra, device 310 can submit a request for data through base station 304 ₂, to which the device 130 is attached; the request for data is a request to consume data. In response to the request for data, and after an identity for base station 304 ₂ has been received via mobility management component 110, CDN platform 150, or one or more components therein, can identify CDN node 302 ₂ through a mapping that associates such CDN node with base station 304 ₂. The mapping can be retained within a memory (e.g., 160) that is available, e.g., functionally connected to or integrated in, CDN platform 150. Further in response, requested data is delivered by CDN 302 ₂ through base station 304 ₂ as described supra.

In a second example scenario, device 320 uploads content to CDN platform 150. Communication path for content upload is illustrated with arrow 324. As described supra, device 320 can submit a request for data through base station 304 ₁, to which device 320 is attached; the request for data is a request to supply data. In response to the request for data, and after an identity (e.g., cell identity) for base station 304 ₁ has been received via at least in part mobility management component 110, CDN platform 150, or one or more components therein, can identify CDN node 302 ₁ through a mapping (e.g., mapping 162) that logically links such CDN node to base station 304 ₁. The mapping can be the same mapping exploited by CDN platform 150, or a component therein (e.g., routing component 154), to identify CDN node 302 ₂ with one or more base stations 304 ₂, 304₃, or 304 ₄. Further in response, requested data is delivered by CDN 302 ₂ through base station 304 ₂ as described supra.

In order to provide additional context for the various embodiments of the subject disclosure, FIG. 4 presents a high-level block diagram of an example network environment in which aspects described herein can be implemented or exploited. Generally, network platform 410 can include one or more components, e.g., node(s), gateway node(s), interface(s), server(s), or platform(s) that enable both packet-switched (PS) (e.g., internet protocol (IP), frame relay, asynchronous transfer mode (ATM)) and circuit-switched (CS) traffic (e.g., voice and data) and control generation for networked communication, wireless or otherwise. In an aspect of the subject disclosure, a functional element within a PS domain of network platform 410 can embody MM component 110 as described herein; PS gateway node(s) 418 can embody at least part the PS domain. In an example scenario, the functional element within the PS domain can enable exchange of MS communications in one or more of the following transport protocols: MMS protocol, SIMPLE, XMPP, or IMPS protocol. With respect to CS communication, network platform 410 includes CS gateway node(s) 412, which can interface CS traffic received from legacy networks like telephony network(s) 440 (e.g., public switched telephone network (PSTN), or public land mobile network (PLMN)) or a SS7 network 460. CS gateway node(s) 412 also can enable exchange of MS communications in SMS protocol. In addition, CS gateway node(s) 412 can authorize and authenticate traffic (e.g., voice) arising from such networks. Moreover, CS gateway node(s) 412 can access mobility, or roaming, data generated through SS7 network 460; for instance, mobility data stored in a VLR, which can reside in memory 430. Furthermore, CS gateway node(s) 412 can interface CS-based traffic or signaling with PS gateway node(s) 418. As an example, in a 3GPP UMTS network, CS gateway node(s) 412 can be embodied, at least in part, in gateway GPRS support node(s) (GGSN).

In the subject disclosure, in addition to receiving and processing CS-switched traffic and signaling, PS gateway node(s) 418 can authorize and authenticate PS-based data sessions with device(s) 428, mobile or otherwise, served through access network(s) 420 via link(s) 425, wireless or wired (e.g., reference links), or wireless link(s) 427. Access network(s) 420 can include base station(s) 120 (not shown), to which CDN platform 150, which can be part of service network(s) 480, can connect via interface(s) 175. Data sessions can include traffic exchange with networks external to network platform 410, such as wide area network(s) (WAN(s)) 450 or service network(s) 480; local area network(s) (LAN(s)) 470 also can be interfaced with network platform 410 through PS gateway node(s) 418. In an aspect, such data sessions can include sessions that include requests for data and data delivery as described herein. Network interface(s) 435 enable the traffic exchange; such interface(s) can include conventional wired or wireless links, or reference links specific to each of the external network(s) that interface with the PS domain, e.g., PS gateway node(s) 418, of network platform. In an aspect, packet-switched gateway node(s) 418 can generate packet data protocol (PDP) contexts when a data session is established. To at least that end, in an aspect, PS gateway node(s) 418 can include a tunnel interface (e.g., tunnel termination gateway (TTG) in 3GPP UMTS network(s) (not shown)) which can facilitate packetized communication with disparate wireless network(s), which can be part of access network(s) 420 and can include Wi-Fi networks, femtocell network(s), macrocellular network(s) and associated radio access network(s) (RAN(s)) based on various radio technology generations, etc. It should be further appreciated that packetized communication can include multiple flows that can be generated through server(s) 414, such as management server(s) (e.g., a provisioning server) or application server(s). It is to be noted that in 3GPP UMTS network(s), PS gateway node(s) 418 (e.g., GGSN) and tunnel interface (e.g., TTG) comprise a packet data gateway (PDG).

In network environment 400, network platform 410 also includes serving node(s) 416 that conveys the various packetized flows of data streams that can be directed to device(s) 428, and that are received through PS gateway node(s) 418 from server(s) 414. In turn, server(s) 414 can receive the communication(s), such as request for data intended to service network(s) 480, or CDN platform 150 therein, from various device(s) (not shown). As an example, in a 3GPP UMTS network, serving node(s) 416 can be embodied in serving GPRS support node(s) (SGSN). As another example, in a 3GPP LTE network, service node(s) 416 can be embodied in a Mobility Management Entity (MME).

Server(s) 414 can operate in various layers of network platform 410, such as Operations Support Systems (OSS), Business Support Systems (BSS), or network sub-systems such as IMS core network, and can execute numerous applications, which can include consumer-oriented application(s), such as messaging services, location services, online gaming, wireless banking, or system-oriented applications, e.g., wireless device management, scheduling or queuing of network traffic, or the like. Such applications, consumer- or system-oriented can generate sets of packetized data streams or flows, and manage (e.g., schedule, queue, format . . . ) such flows. Such application(s), for example can include add-on features to standard services provided by mobile network platform 410. Data streams generated by server(s) 414, can be conveyed to PS gateway node(s) 418 for authentication/authorization and initiation of a data session, and to serving node(s) 416 for communication to device(s) 428 thereafter.

Server(s) 414 also can also effect security (e.g., implement one or more firewalls) of network platform 410 to ensure network's operation and data integrity in addition to authentication and authorization procedures that CS gateway node(s) 412 and PS gateway node(s) 418 can enact. In addition, server(s) 414 can implement timing protocols (e.g., Network Time Protocol (NTP)) that supply timing framework(s) for various operation(s) of network platform 410. Moreover, server(s) 414 can provision services from external network(s), e.g., WAN 450, IMS core network which can be part of service network(s) 480, or Global Positioning System (GPS) network(s) (not shown). Server(s) 414 can include one or more processors (not shown) configured to provide at least in part the functionality of network platform 410. To that end, the one or more processor can execute code instructions (not shown) stored in memory 430, for example.

In example network environment 400, memory 430 can store information related to operation of network platform 410. Information can include content(s), such as subscriber-generated content or from various other sources; subscriber account(s) and associated credential(s); pricing schemes, e.g., promotional rates, flat-rate programs, couponing campaigns; and so forth. Memory 430 can also store information from at least one of telephony network(s) 440, WAN(s) 450, LAN(s) 470, SS7 network 460, or service network(s) 480. As illustrated, memory 430 also can include database(s) 140. While illustrated as a single entity, memory 430 can be distributed amongst one or more of the described external networks, server(s) 414, or other functional elements of network platform 410.

FIG. 5 is a call flow of an example method 500 for providing data to a device, mobile or otherwise, in accordance with aspects described herein. As illustrated, various functional elements of example system 100 can implement, at least in part, various acts includes in the subject example method 500. To provided data, or content (e.g., web-based content), device 130 delivers a request for data at act 505. The request for data is received by based station 503, which relays the data request to mobility management (MM) component 110 at act 510. The request for data can be tagged, or otherwise labeled or logically associated, with an identifier (ID), such as a cell identity for the base station that received the request for data from device 130. Mobility management component 110, at act 515, conveys the tagged request for data to routing component 154, which at act 520 maps the ID of the base station to a CDN node; in an aspect, such CDN node is deployed in geographical proximity of the base station 503 that receives the request for data. In one or more alternative embodiments, mapping component 156 can map the ID of the base station to the CDN node 501. At act 525, routing component 154 delivers the request for data and a service constraint indication, or QoS indication, based on at least one of the CDN node 501 or operational condition(s) thereof. At act 530, the CDN node 501 receives the request for data and delivers payload data according to the received service constraint indication. The payload data is delivered to base station 503, which transmits the payload data to the device 130 at act 535.

FIG. 6 illustrates a call flow of an example method 600 for collecting, e.g., uploading, data into a CDN according to aspects described herein. Data can be collected from device 130, which delivers a request for data at act 605. The request for data is delivered to a base station 603 and includes a request to transmit payload data to the CDN. At act 610, base station 603 communicates the request for data to MM component 110, which relays, at act 615, the request for data and an identifier (ID) of the base station that delivered the request for data. The request for data and the ID of the base station 603 can be received at routing component 154, which at act 620 can map the ID of the base station to a CDN node 601 linked to the identified base station. In one or more alternative embodiments, mapping component 156 can map the ID of the base station to the CDN node 601. As described supra, the CDN node 601 can be in geographical proximity of the identified base station. In addition, routing component 154 can assign a QoS configuration or a service constraint indication based on at least one of the CDN node 601 or operational condition(s) thereof. At act 625, routing component 218 transmits the request for data and QoS configuration, or the service constraint indication, to CDN node 601. At act 630, CDN node 601 delivers an indication to serve the request for data according to the QoS configuration, or the service constraint indication. Such indication is delivered to the base station 603 that received the request for data from device 130. At act 635, the base station 603 communicates a request for payload data. In addition, the base station 603 can configure, or allocate, radio resources for telecommunication with device 130 according to the QoS configuration, to ensure a specific quality of service for receiving the payload data. In response to such request, device 130 conveys payload data at act 640. Base station 603 forwards the payload data to CDN node 601 at act 645. To retain the payload data in the CDN (e.g., CDN platform 150), CDN node 601 can deliver the payload data to routing component 154 at act 650.

FIG. 7 is a flowchart of an example method 700 for routing data in a CDN in accordance with aspects described herein. The subject example method can be implemented, at least in part, by one or more components within a CDN platform; e.g., routing component 154 and mapping component 156 can effect the subject example method 700. One or more processors also can be perform the subject example method. In an aspect, the one or more processors can provide, at least in part, the functionality of the routing component 154 or component(s) therein. In another aspect, the one or more processors can execute the routing component 154 and the mapping component 158, if the routing component 154 and the mapping component 156 are embodied in a set of code instructions, which can be part of a software application or a firmware application.

At act 710, a request for data that includes an identity, or identifier, of a base station is received. In an aspect, receiving the request for data includes receiving the request for data indirectly from a mobile device (see, e.g., FIGS. 5-6) that originates the request for data and communicates wirelessly with the base station. In another aspect, in one or more additional or alternative embodiments, the request for data may be received directly from the mobile device; for instance, depending on the architecture of a CDN platform (e.g., 150), the mobile device can wirelessly deliver the request for data to the CDN platform. As described supra, the identity or identifier can be at least one of a cell identification, a sector identification, or a logical address (e.g., IP address) for the base station. The request for data can be a request to consume, e.g., receive or download, content (e.g., web-based content). At act 720, a content node associated with the base station is identified; the content node is part of a set of nodes deployed within a content distribution network (CDN). In an aspect, the content node is identified through a predetermined mapping. The predetermined mapping establishes a relationship amongst the content node with one or more base stations provisioned and active to provide service to a mobile device; the relationship amongst the content node and the one or more base stations can be a one-to-one relationship or a one-to-many relationship. In another aspect, the content node identified through the mapping is located within a predetermined geographical distance from the base station; thus, identifying the content node includes selecting the content node in a content distribution network that is located within a predetermined geographical distance form the base station. At act 730, in response to the request for data, such request for data is directed, or routed, to the content node. In addition, a service constraint indication to serve the request for data is supplied. In a scenario, if the request for data is a request to consume data (e.g., content), the service constraint indication can be a QoS configuration (e.g., a QoS class, or a predetermined bit rate or upper bound or lower bound thereof) to deliver payload data solicited in the request for data. In an alternative scenario, if the request for data is a request to supply data (e.g., content), the service constraint indication can be a QoS configuration to receive payload data (e.g., content) associated with the request for data.

FIG. 8 is a flowchart of an example method 800 for supplying data in a CDN in accordance with aspects described herein. The subject example method 800 can be implemented, at least in part, by a CDN node, or component(s) therein.

At act 810, a request for data is received. As described supra, the request for data can include an identity, or identifier, of a base station that serves (e.g., communicates wirelessly with) a mobile device that originates and delivers the request for data. The identity or identifier can be at least one of a cell identification, a sector identification, or a logical address (e.g., IP address) for the base station. In an aspect, receiving the request for data includes receiving the request for data directly or indirectly from the mobile device that originates and delivers the request for data. It is noted that while in one or more embodiments of a CDN node, or component(s) therein, that implement the subject example method 800, the request for data is received indirectly (see, e.g., FIG. 1 or FIG. 6), in additional or alternative embodiments, the request for data may be received directly from the mobile device. At act 820, a service constraint configuration (e.g., a QoS configuration) for delivery of payload data solicited in the request for data is received. In an aspect, the service constraint configuration can be based on operational condition(s), e.g., load, of the CDN node that can effect the subject example method 800. At act 830, the payload data solicited in the request for data is delivered according to the service constraint configuration. The subject act 830 can be part of an act of serving the request for data according to the service constraint indication if the request for data is a request to consume data; the one or more processors that can implement the subject example method 800 can carry out such serving act.

At act 910, a request for data and a service constraint, or service constrain indication, to serve the request for data are received. In an aspect, the request for data can be a request to supply (e.g., upload) content, such as a digital file, which includes a file for specific applications that can be executed in a requestor device (e.g., 130), or a digital media file (video, picture, sound, etc.), or the like. The request for data can originate in a device that can communicate wirelessly with a base station. At act 920, an indication to serve the request for data according to the service constraint is delivered to a base station identified in the request for data. The subject act 920 can be part of an act of serving the request for data according to the service constraint, or service constraint indication, if the request for data is a request to supply data (e.g., content); the one or more processors that can implement the subject example method 900 can carry out such serving act. At act 930, payload data that results from serving the request for data is received. In an aspect, the payload data is received from the base station the communicates wirelessly with a device that delivers the request for data. At act 940, the payload data is transmitted.
